BODY AS-PISTON 5510841 - Caterpillar

1.1: Engine Control
* Fully electronic eight notch engine speed governor.* Low idle notch engine speed governor setting.* Dual engine speed ramp rates for switch-yard and main-line operation.* Smoke limiting rack schedule during engine start.* Dual engine speed for low and high levels of dynamic braking.1.2: Traction Power Control
* Low notch traction power control (typically in notches one thru three).* High notch gross engine power control (typically in notches four thru eight).* Load test mode.* Generator voltage limiting.* Generator current limiting.* Differential wheelslip regulation.* Synchronous wheelslip regulation.* Traction motor current limiting.* Traction motor current matching (performance control).* Automatic sanding.1.3: Dynamic Brake Control (If Equipped)
* Grid current regulation.* Field current regulation.* Differential wheelslip regulation.* Automatic sanding.* Grid cooling fan failure alarm.* Grid current alarm.1.4: Engine Protection
* Linear power derate with high coolant temperature (through traction power control).* Step power derate with high coolant temperature (backup to the linear derate through traction power control).* Linear power derate with low barometric pressure (through traction power control).* Low oil pressure shutdown.* Overspeed shutdown.* Automatic drop out of starter motors.* Starter motors inhibited from engagement with engine running.* High crankcase shutdown (if equipped).* High coolant temperature alarm.1.5: Maintenance
* Comprehensive fault diagnostic indications.* Fault tolerant (limp home current limits) under certain conditions of sensor/harness failures.* Fail-safe strategy (zero excitation) in event of multiple sensor/harness failures.* Each individual module in the electronic governing system is pre-calibrated for reliable and easy maintenance.* Emergency shutdown annunciation outputs available.
